Hosta plant named ‘B200’

ABSTRACT

A new cultivar of Hosta named ‘B200’ that is characterized by its variegated foliage with yellow-gold centers in color and green margins with some streaks of green into the centers, its leaf margins that are ruffled, its vigorous growth habit, and its high tolerance to sun scorch.

Botanical classification: Hosta hybrida.

Cultivar designation: ‘B200’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hosta, botanically of hybrid origin and known as a Hosta ‘B200’ and is hereinafter referred to by its cultivar name ‘B200’.

The new cultivar was discovered by the Inventor in May of 2012 as a naturally-occuring chimeral mutation of Hosta ‘Dancing Queen’ (not patented) that was growing in a container outdoors in Barneveld, The Netherlands.

Asexual propagation of the new cultivar was first accomplished by division by the Inventor in Barneveld, The Netherlands in 2013. Asexual propagation of the new cultivar by division and tissue culture using meristematic tissue has shown that the unique features are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘B200’ as a new and unique cultivar of Hosta.

-   -   1. ‘B200’ exhibits variegated foliage with yellow-gold centers         in color and green margins with some streaks of green into the         centers.     -   2. ‘B200’ exhibits leaf margins that are ruffled.     -   3. ‘B200’ exhibits a vigourous growth habit.     -   4. ‘B200’ exhibits a high tolerance to sun scorch.

The parent plant, ‘Dancing Queen’, differs from ‘B200’ in having a shorter plant height and in lacking variegated foliage. ‘B200’ can be most closely compared to the Hosta cultivars ‘On Stage’ (not patented) and ‘One Last Dance’ (U.S. Plant patent application Ser. No. 15/530,300). ‘On Stage’ is similar to ‘B200’ in having a similar leaf variegation with yellow-gold centers and green margins. ‘On Stage’ differs from ‘B200’ in having a shorter plant height, leaf margins that are not ruffled, and in having a more upright plant habit. ‘One Last Dance’ is similar to ‘B200’ in being a chimeral mutation of ‘Dancing Queen’. ‘One Last Dance’ differs from ‘B200’ in having the reverse leaf variegation pattern by exhibiting green centers and yellow-gold margins.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hosta. The photographs were taken of 2 year-old plants as grown outdoors in a 27-cm container in Barneveld, The Netherlands.

FIG. 1 provides an overall view of the plant of ‘B200’.

The photograph in FIG. 2 provides a close-up view of an inflorecence of ‘B200’.

FIG. 3 provides a close-up view of a leaf of ‘B200’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Hosta.
